Note l — BOOK IV.

It is remarkable, that in most, if not all Animals, whose Ears are tunnelled, or where the Meatus Auditorius is long enough to afford Harbour to Ear-wigs, or other Insects; that, I say, in the Ears of such, Ear-wax is constantly to be found. But in Birds, whose Ears are covered with Feathers, and where the Tympanum lies but a little way within the Skull, no Ear-wax is found, because none is necessary to the Ears so well guarded, and so little tunnelled.
